Trans-radial approach (TRA) has been used in cardiac and peripheral interventional radiology practices for decades, because of safety and patient comfort. There is interest in TRA in the cerebrovascular field, with potential to replicate benefits over trans-femoral approach. TRA is technically more challenging and has a learning curve, which hinders its use as the first-line approach; however, as more neuro-interventionalists embrace TRA, techniques are being optimized simultaneously for supra-aortic vessel catheterization. This article describes advantages, patient selection, conventional and distal radial access, and detailed techniques of trans-radial catheterization for diagnostic angiography, as well as cerebrovascular interventions and its current limitations.
经桡动脉途径（TRA）由于其安全性和患者舒适度，已在心脏和外周介入放射学实践中使用了数十年。脑血管领域对TRA也有兴趣，有可能复制其相对于经股动脉途径的优势。TRA在技术上更具挑战性且存在学习曲线，这阻碍了它作为一线途径的使用；然而，随着越来越多的神经介入医生采用TRA，用于主动脉弓上血管插管的技术也在同步优化。本文描述了经桡动脉插管进行诊断性血管造影、脑血管介入治疗的优势、患者选择、传统及远端桡动脉入路和详细技术，以及其当前的局限性。
